  • Resumen
    • We consider the optimization problem of minimizing in the class of functions W1,G(O) with , for a given f00 and bounded. W1,G(O) is the class of weakly differentiable functions with . The conditions on the function G allow for a different behavior at 0 and at 8. We prove that every solution u is locally Lipschitz continuous, that it is a solution to a free boundary problem and that the free boundary, On?{u>0}, is a regular surface. Also, we introduce the notion of weak solution to the free boundary problem solved by the minimizers and prove the Lipschitz regularity of the weak solutions and the C1,a regularity of their free boundaries near �flat� free boundary points.
